Description
Technical field
The utility model belongs to machine tool field, specifically, relates to the lathe of a kind of self-centering end face milling, centering and cover turning.
Background technology
In machining, thin and long shafts is forged to the turnery processing of blank, its processing step is generally: 1) the flat biend of first milling, controls total length; 2) line centering, centering; 3) upper lathe four-jaw chuck clamp one end head blank, one end tail stock is top in addition withstands centre bore; By lathe chuck four paws adjustment centering blank axis cylindrical surplus, rough turn slender axles cylindrical; 4) unclamp lathe chuck, unclamp tail stock top, unload slender axles, aerial tune 180 degree; 5) second time clamping is carried out, generally to change the lathe that has three-jaw self-centering chuck, clamp the cylindrical of rough turn mistake with three-jaw self-centering chuck, withstand centre bore with tail stock is top, by the boule portions size of chuck clamping during original first time clamping.Because traditional handicraft needs once to unload workpiece again in addition, reverse end for end 180 degree of reprocessing, employing secondary lifting workpiece, secondary clamping, the method for secondary operations.Need the lathe of a chuck lathe and a three-jaw self-centering chuck in addition respectively.Cold roll is elongated, and draw ratio is generally at about 7-8, heavier, and workman's lifting workpiece is very inconvenient, also can take mutually the shared driving in workshop in usual batch machining, and often have and wait for shared driving phenomenon, waste process time, production efficiency is lower.Especially to there being the diminished shaft class of 3 ~ 5 degree of taperings to forge blank workpiece (as Fig. 4 shows taper work roller part), position of bearings blank due to two ends is that flat-die forging is shaping, with mid portion blank meeting disalignment, therefore there is the problem being difficult to line centering and centering, so line centering is pretty troublesome, time-consuming.Major part enterprise often adopts on mechanical processing technique first makes the consistent cylinder blank of concentric reducer by cone, and then it is tapered by machining, such blank allowance is just very large, has both added material cost and has turn increased forging and machining time, cost.
China Patent No. 2013206468891, the patent document in publication date on May 7th, 2014, disclose a kind of lathe, it cutter for cutting comprising lathe body, lathe spindle, tail stock and be fixed on lathe saddle, the inner side of described lathe spindle is installed square top, the inner side of described tail stock is installed and is rotated top, and the position that described square top with described rotation is top is relative, and the top axial line of described square top with described rotation overlaps.This utility model can realize completing turnery processing to workpiece clamped one time, avoid the error that multiple clamping causes, improve the machining accuracy of workpiece and the utilization rate of lathe, effectively saved the processing cost of workpiece, greatly reduce the labour intensity of operator, improve operating efficiency.This utility model relies on two top pressure fixation workpieces, weight can be processed little, the workpiece that length is little, but to forging the larger workpiece of draw ratio and weight blank workpiece as cold roll, only adopt top stability maintenance poor, there is potential safety hazard.
Chinese Patent Application No. 201320722069.6, the patent document in publication date on April 16th, 2014, disclose a kind of numerical control end-face milling centering lathe, comprise lathe bed, left workbench, right workbench, middle italic workbench, numerical control operating case and housing, it is characterized in that: the face, upper left of lathe bed is provided with left workbench, the upper right face of lathe bed is provided with right workbench, middle part above lathe bed is provided with middle italic workbench, left workbench, right workbench, the outside of middle italic workbench is covered with housing, before housing, side is provided with numerical control operating case, middle part before housing is provided with a moving door.The beneficial effects of the utility model are, easy to operate, and operating efficiency is high, workbench steadily of centre of gravity, and guide rail rigidity is strong, long service life, produce, mounting process is simple.Precision is easy to control, and manufacturing time is short, is covered with housing outside workbench, and reach 100% totally-enclosed protection effect, security is high.Adopt 75 ° of italic structural designs, good rigidly, chip removal is very smooth, more time saving and energy saving.When processing draw ratio and the larger workpiece of weight as cold roll forges blank workpiece, namely this utility model allows to complete above-mentioned steps 1 simultaneously) and step 2) in the processing technology of end face milling and centering, but still keep away unavoidable step 3), step 4) and step 5) loaded down with trivial details technique, still need during turning to carry out secondary clamping to workpiece, secondary turning, waste human and material resources and production time, reduce production efficiency.
Technical scheme disclosed in above-mentioned two parts of patent documents all automatically can not complete and forge the self-centering end face milling of blank workpiece, centering and cover turning with 3 ~ 5 degree of diminished shaft classes.Add the manual alignment of man-hour requirement, draw centre bore by hand, still need during turning to carry out secondary clamping, secondary turning to workpiece, waste time and energy, reduce operating efficiency.
Summary of the invention
The problem that 1, will solve
During for prior art processing draw ratio and weight larger shaft-like workpiece, need secondary clamping, secondary turning, waste human and material resources and production time, production efficiency is low and automatically can not complete the problem that 3 ~ 5 degree of tapers or small one and large one two Step Shaft classes forge blank workpiece centering end face milling, centering and cover turning.The utility model provides the lathe of a kind of self-centering end face milling, centering and cover turning, cylinder, cone shaft-like workpiece end face milling, centering and scroll chuck bare terminal end blank cylindrical can be completed to harness an animal to a cart turning process simultaneously, this workpiece is made only to need the position of harnessing an animal to a cart with scroll chuck clamped one time at the outer bowlder of subsequent turning, one-time turning cylindrical completes, substantially increase operating efficiency, alleviate manpower, and save a large amount of raw material and forging, machining cost.
